The present study used immunohistochemical staining and in situ hybridization (ISH) to examine whether progression of cervical intraepithelial neoplasia, grade 2 (CIN 2) can be predicted by p16INK4a immunoexpression and high-risk human papilloma virus (HPV) ISH signal types. We studied 52 cases histologically diagnosed with CIN 2: dysplasia regressed in 28 cases; 13 cases progressed to CIN 3; and CIN 2 persisted in 11 cases. Expression of p16INK4a and high-risk HPV signal both related to grade of CIN. Stronger p16INK4a immunoexpression and a higher frequency of expression of a punctate nuclear signal were observed in CIN 2 lesions before progression compared with those before regression. CIN 2 cases in which moderate to strong immunoexpression of p16INK4a and a punctate signal were observed simultaneously progressed to CIN 3 in 10 (91%) of 11 cases. CIN 2 cases with moderate to strong immunoexpression of p16INK4a and a high-risk HPV punctate signal should be treated because of the great risk of progression.
